Located in Japan, the Shell House is a sculptural large shell shaped structure that built in the woods of Karuizawa, located in Kitasaku, Nagano. The Shell House was designed by Japanese Architect Kotaro Ide, ARTechnic Architects, the concrete home building comprises two tubes with oval sections is meant to function as a vacation home, which is able to withstand the humid summers and cold winters of the region. To accomplish this, Kotaro Ide opted not to use the typical wood structure of two-storey house design in the area because of their susceptibility to decay easily.

The villa’s simple aesthetic lends itself well to the traditional Japanese landscape, creating a balance between the futuristic man-made structure and the environment which surrounds it. The entire project took more than 18 months to realize and two and a half years to complete.
